RESUMEN
INTRODUCTION: The anatomical complexity of the temporal region makes it so treatments with fill-ins are challenging due to high vascular risk. Techniques which provide safer procedures must be encouraged. GOAL: Suggest access to the temple through the inferolateral orbital region as a means for safer temporal fill-ins. METHODS: The fanning technique was plotted out not only via the conventional access (pretragal) but via the proposed one as well. The superficial temporal artery (STA) was mapped with ultrasound. The angles for each of the five retroinjection vectors were calculated in relation to STA and their mean was extracted. The longitudinality of the vector in regard to the vessel was considered the least safe factor. RESULTS: The mean injection angle towards the artery was a 35-degree angle for the conventional access technique and a 73-degree angle for the inferior-lateral orbital access technique (p < 0.05). The more a degree is tangential to the vessel, the higher the chances for inadvertent puncture due to small technical issues. The safety of the procedure through the inferolateral orbital access is corroborated with blind ultrasound imaging done in real-time by radiologists. CONCLUSION: The suggested access is shown to be comparably safer from a vascular perspective than the conventional pretragal access.
